Blender doesnt render any shadow
Your lights are de-activated in the viewport - No light, no shadow (click the eye icon)
Emission shaders don't receive shadows
If you plug a color into the output of a shader, it is automatically converted to an emission shader. Try with a principled bsdf or a diffuse shader
Your scene is not up-to-scale. Your couch is 3 meters high and 9 meters wide. The lighting won't be realistic if you don't try to respect realistic proportions
Turn way up the power of your point light


If you want a cartoony look you can use the &quot;Shader to RGB&quot; node after the shader. Also use ambient occlusion to add to the realism
